Venus and Mercury in the predawn twilight

After many days of cloudy weather, yesterday morning (January 12, 2011) I did not want to miss the rare occasion of clear sky so one and a half before hour dawn moved to a hill with an open view over the eastern horizon of Turin (Italy) to try to capture Venus and Mercury just few days after their greatest elongation from the Sun (that occurred on the 8th and 9h of January, respectively). When I arrived, Venus was already very high in the sky, shining at a -4.4 magnitude!, directly above the reddish Antares in Scorpius, whereas Mercury was still immersed in the pre-dawn twilight glow but easily detectable with naked eyes.
This beautiful morning scene was worth an early wake!

I, too, thought that your Pleiades picture was lovely, Alan Chen.

But I couldn't find the cat!

The moon sets behind the Arrábida's Mountain range, as do many trails from well-known stars, including the Pleiades in the top center above the moon and the constellation Cassiopeia in the right corner. Also in the image are trails from Andromeda, Aries, Cetus, Pisces and Triangulum. On land, the strong light of the moon illuminates the beach Portinho da Arrábida facing the Atlantic Ocean.

Because the cat is the one of Emil Ivanov, not of Alan Chen

There it is!
I also put a picture of the Large Hadron Collider, taken while it was still under construction.

Eta Carinae Nebula

one of my last images from Namibia, I am missing so much the sky down there...I hope you like it

zema88, that is a very elegant portrait of the Pleiades, particularly in view of the non-favorable weather conditions. And it is a lot of fun to see the asteroid among the sisters!

Michael Siniscalchi, I so rarely like pictures of planetary nebulae, but I like yours. Your portrait brings out many interesting structural details in the nebula, and I love the colors. The nebula is red, pink and dust-brown, and in the center there is that deep dark blue-green hue from a bit of oxygen emission. It is interesting to see that the central star of the nebula is by far the bluest object in the picture, which is what we would expect from such a hot object. Interestingly, though, the blue color is slightly tinged with green. Is it possible that the green color of the OIII emission, through which we see the central star, affects the apparent color of the blue-hot white dwarf? I'm asking because there appears to be a spiral galaxy peeking though the central "hole" of the planetary, and the galaxy appears suspiciously greenish, as if its color had been affected by the thin green-glowing gas in front of it. Well, very interesting in any case!

Adam, your image is great, like all your deep-space pictures. Since the Orion Nebula is perhaps the most-photographed deep-space object of them all I'll refrain from commenting much on the picture, except to say that the colors are very fine and the structural details beautiful. I particularly like the dust lanes in the nebula called M43. These dust lanes almost look like a network of fine arteries. However, the detail I find most interesting is the distribution of small stars in the deep red background. In some parts there appears to be a wealth of small stars, but in other parts there are far fewer of them. I have to wonder if the small stars are background objects, which in some places can be seen clearly and in other places are hidden by dust, or if they are the products of earlier bursts of star formation here.

Nicola Montecchiari, that is a very beautiful portrait of the Eta Carina Nebula, particularly the high-resolution image. I like how you bring out the different color and texture of the different "lobes" of the nebula. I like the impressive appearance of the great NGC 3293 cluster in the far left corner of your picture. The cluster looks very rich, and some wisps and tatters of all the gas that went into making it are still visible around it.

Beautiful Moon image(s). Thank you for posting it!

Ann · Post by **Ann** » Sun Jan 16, 2011 4:54 pm

Emil Ivanov, that's a fantastic image of a Perseid making a "bulls-eye" at the Pleaides! The meteor appears to aim for, or originate at, Alcyone, the brightest star of the Pleiades and the very "heart" of the Seven Sisters, if such a "heart" exists. And what a delightful color contrast between the very blue Pleiades and the white and green Perseid!

Hi Ann,

Thank you for the critique. I have a new Samsung LCD monitor that replaced my CRT and am still dealing with trying to get good color and gamma settings despite using a Spyder and QuickGamma. I'd love to go back to a CRT if I only could find one!
I went back to the image and found the blue central star did lean slightly to green using the PS eyedropper to measure. You sure have a good eye for hue. Going back to the color frames to check and found the galaxy too had too much saturation in the posted version. I adjusted both and now feel this is how "it ought to look" though I suspect that anything behind the gasses may take on a slight color tone towards that spectrum depending on its own intensity.
This planetary has always intrigued me but due to its very low surface brightness and no examples on the web with log exposures, I was curious as to what the pillar looking structures inside were. After putting a lot of exposure time into the Lum and Ha channels, it's now clear that these seemingly inner pillars are actually outer dust structure surrounding the nebula.

Thank you again for your comments,
Mike Siniscalchi
